2 Claims. (Cl. 242--55.5).

This invention relates to new and useful imable cutter blade 15 of the shape shown in Figure provements in paper cutters. 6. Formed inwardly from the ends of this blade It is the principal object of this invention to are ears 16, each one of which has a large aperprovide for wrapping paper cutters, a guard havture 17 and a small aperture 18.

Figure 2 is an end register with the small apertures 18 in the blade view of the same, partly in section, showing one ears 16 to receive rivets 24 by which the guard is of the swinging, supporting arms as a stamping firmly secured to the blade as shown in Figures for the gravity brake bar. Figure 3 is a similar 1, 2 and 3.

This rod ger piece 26. Unless the blade is moved inwith the cutting edge of the blade, is difficult to grip. This rearward movement of the blade to expose a gripping edge of the paper, is accomplished with absolute safety, since the guard is connected to the blade to swing with it to the dotted line position shown in Figure 2 and thereafter return to its normal cutting position. The relation of this guard member 20 to the blade at all times, protects from injury those who operate the cutter, or come near it when attending to other duties.

Having described my invention, I claim:

1. A paper cutter comprising a frame, a shaft journaled therein and supporting a roll of paper, a rod transversely mounted in said frame in front of said roll, a cutting blade having projecting ears pivotally mounted on said rod, whereby the blade has a swinging movement thereon, and a U- shaped member whose ends are secured to said ears for a swinging movement with said blade, the bottom part of the U-shaped member being spaced from the cutting edge of the blade to form an opening through which the paper may be safely and easily drawn.

2. A paper cutter comprising a frame, a shaft journaled therein and supporting a roll of paper, a pair of spaced arms pivotally mounted at their inner ends in said frame, a cutting blade carried by the free ends of said arms, each arm having an enlarged portion behind its blade carrying part, the enlarged portions of said arms formed with oppositely disposed vertical slots, a transverse member fixed between the free ends of said arms below said slots, and a gravity brake bar vertically movable in said slots, to engage the paper over said transverse member.
